6 report Anita Dey Thursday 8am Abstract: We recently performed a liquid nitrogen experiment in finding the Latent heat of the substance. We isolated two parts of the experiment in order to find out how much evaporation of the liquid nitrogen was from the surroundings B and how much evaporation from the electricity G. 1. When a substance is undergoing a phase transition‚ more heat (energy) is being added to the Substance but its temperature (a way of measuring its energy) is not changing. Where

we are in any given moment. These fragments of ourselves include our sexuality‚ gender‚ and sense of belonging to a particular culture‚ nation‚ religion‚ family‚ or some other group. Our identity includes our looks‚ personality‚ beliefs and fears. Our identities are constantly growing‚ changing‚ and adapting to our everyday lives. This emphasizes the overriding link that one’s sense of belonging influences‚ or often dictates‚ individual identity. Each individual in society assigns themselves a particular

lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass of water‚ ΔT represents

Ailine Veiga Question: what is the heat of fusion of ice? Hypothesis: To get the heat of fusion of ice we need to determine the Energy it takes to melt the ice and also the mass of the ice and determine the heat of fusion. To determine the mass of the ice melted (m) we start by determine the volume of the water generated when the ice melted. This is the difference between the final volume (v2) and the initial volume (v1). Using the density of water (1.0g/mL)‚ this volume can be converted into mass

PROMPT: What could be the advantages/benefits of belonging to a group or groups or to a community? The advantages of belonging to a group or groups can have a lot of advantages and benefits. Being apart of a group(s) we are able to see who we want to be and do rather then who we try to be and to fit in. There’s always a group that can be influential‚ good or bad. The shaping of our identity is aided by various influences in our lives‚ one of them being the groups to which we belong. “Who am I

Prompt: Belonging to a group both strengthens and weakens our sense of self. The shaping of our identity is aided by various influences in our lives‚ one of them being the groups to which we belong. There are different types of groups which we may find ourselves associated with‚ such as social‚ religious and cultural groups. Belonging to any one of these groups may be either by choice or a sense of obligation. For instance‚ the decision to belong to a certain social group is entirely dependent
